AXLE.

Specification of Letters Patent.

Patented Aug. 22, 19111.

Application filed December 8, 1909. Serial No. 532,602.

To alt whom it may concern:

Be it known that I, lnxamnx A. Gann snN, a citizen et the United States, residing at Sioux Falls, in the county et Minnehaha and State olf South Dakota, have invented new and useful lmprevements in Axles, oit which the following is a specilication.

The invention relates to an improved axle, being more particularly directed to a construction whereby the lubrication oit the wheel mounted on the axle may be simply and expeditiously accomplished by directing iter such lubrication any desired portion et `the lubricant carried by the axle.

The main, object of the present invention is the provision et an axle formed to provide a lubricant chamber in which is stored a quantity of more or less solid lubricant, the chamber communicating with the exterior or bearing surit'ace oit the axle by means of a plurality of channels, the construction including a simple means whereby the lubricant in the chamber may be 'forced lengthwise the same to feed the lubricant out through the channels.

The invention in its preferred details et construction will be described in the iollewing specification, reference being had particularly to the accompanying drawings, in which the figure comprises a sectional view, partly in elevation, showing the axle and wheel hub cooperating therewith.

Referring particularly to the accompanying drawing, my improved axle comprises a metallic body l designed to be secured upon the terminal of a wooden axle 2 in the usual manner. For this purpose l pret'er to provide the wooden axle with a comparatively short projection 3 designed to tit an opening l formed in lthe body, the portion of the contacting surfaces et the projection and opening being inclined at 5 to insure a proper position ott the axle l to advair tageously locate the lubricant channels hereinafter noted. rlhe metallic axles are provided with the usual annular' flanges (i, the flange ot one axle being connected by a truss red 7 with the flange of the other axle to secure them in applied positions.

In advance et the opening 4iin the metallic axle, the latter is termed with a longitudinal bore S interiorly threaded at 9 and hereinafter termed the lubricant chamber. The chamber 8 opens through the :toi-ward end of the metallic axle and terminates at its rear end slightly in advance of the torward end et the opening -l-. A solid plug l0 is designed 'tor threaded connection with the wall et the chamber, said plug operating as a plunger to 'torce the lubricant longitudinally et the chamber, as will presently appear. Adjacent the rear end oi the lubricant chamber the metallic axle is :termed with divergent channels lll which communicate at their inner ends with the chamber and open at their outer ends through relatively spaced portions ot the metallic axle. The inclined portion 5 et the metallic body 'terms one wall oitI one et the chambers 'l1 and the said inclined portion serves the double purpose ot insuring the proper position oil' the axle 3 with respect to the metallic body l and provides means whereby the ll'lbricating channels may be properly located.

The wheel hub 12 is interiorly provided with the usual boxing 13 designed to lit and bear upon the outer surface et the body l, the boxing being secured against endwise movement on the body by the usual nut llt.

l'n use, solid or semi-selid lubricant 15 is arranged in the chamber 8 and the channels ll. are also preferably filled with such lubricant. The plunger plug l() is inserted, be ing :termed to permit operation by any suitable type et wrench. lVhen it is desired to lubricate the wheel the plunger is screwed into the chamber forcing the lubricant therein through the channels '11, directing such lubricant between the boxing and sur- 'liace el the axle.

lt is obvious that a comparatively large quantity et lubricant may be carried in each axle and that su'llicient tor each days lubrication .may he forced Ytrom the channel by a comparatively small inward movement ol the plunger. By this means and theuse et a conveniently carried wrench, any wheel may be readily and conveniently lubricated at any time or place in a simple, expeditious manner.

The invention is applicable to any wheel vehicle, and in this connection it is to be noted that the channels ll open upwardly lrom the chamber .so that a semi-solid lubricant may be used as conveniently and as expeditiously as a solid one.

.llaving thus described the invention, what is claimed as new, is:

An axle formed with a diametrically reduced extension, said extension being formed in part to provide an inclined surface, a nietallic body adapted to be positioned upon the axle and projected beyond the saine to receive and support a wheel, said body being hollow for a portion of its length, the wall of said hollow portion being fornied in part to provide an inclined surface to cooperate with the inclined portion of the axle projection to fix the position of the body on the axle, said body in advance of the hollow portion being formed with a longitudinal bore communicatingwith the surface of the body through a plurality of diverging channels, one of said channels being parallel to the inclined wall of the hollow portion of the body, one wall of said channel being forined by said inclined wall of the body, and a plug having threaded engagement with the interior of the bore whereby the lubricant may be de.- livered to said channels, and distributed on the axle.

In testimony whereof I aiiix my signature in presence of two witnesses.
